Description

Technical Field

[0001] This utility model relates to the field of rolling door motor technology, and more specifically, it relates to a rolling door motor for rolling shutter doors with fireproof function. Background Technology

[0002] Fire-resistant roller shutter doors are vertically adjustable fire-resistant partitions consisting of metal curtain panels, guide rails, a motor, and a control system. They are normally rolled up and concealed, but automatically or manually lowered in case of fire, forming a fire-resistant barrier. The curtain panels are typically made of galvanized steel or inorganic fiber composite materials, with a fire resistance rating of 1-3 hours (compliant with GB14102 standard). They also provide heat insulation and smoke protection, and are widely used in fire compartments in large opening areas such as shopping malls, garages, and factories. Some products are equipped with temperature and smoke detector linkage devices that work in conjunction with the fire protection system to ensure rapid response in case of fire.

[0003] In most existing fireproof rolling shutter doors, the drive unit in the rolling shutter machine is directly fixed to the bracket structure with bolts. This requires repeated disassembly and tightening of the bolts during maintenance, making maintenance inconvenient and inefficient. Utility Model Content

[0006] A fire-resistant roller shutter door motor includes a mounting frame, with two sets of mounting frames symmetrically arranged. A winding shaft is connected between the two sets of mounting frames via bearings. A fixed frame is provided at the bottom end of one mounting frame, and a driving device is mounted on the fixed frame. A chain drive structure is provided between the driving device and the winding shaft. The motor also includes a mounting plate, with a fixed seat on the mounting plate. A clamping seat is hinged to the fixed seat, and a fixed ear is provided on the fixed seat. A locking ear is provided on the clamping seat, and a locking structure is provided between the locking ear and the fixed ear. The driving device is located between the fixed seat and the clamping seat. Mounting bolts are provided between the mounting plate and the fixed frame, and a positioning protrusion is provided on the back of the mounting plate. A positioning groove is provided on the fixed frame.

[0007] The present invention is further provided with a protective cover on the outside of the mounting frame and the drive device, a lifting groove at the bottom of the protective cover, and a fireproof and heat-insulating film inside the protective cover. The protective cover can improve the external protection effect of the mounting frame, drive device, mounting shaft and other components, and the fireproof and heat-insulating film can improve the overall flame-retardant and heat-insulating effect. The fireproof and heat-insulating film can be made of aluminum foil film or glass fiber base film.

[0008] The present invention is further configured such that the driving device includes a central motor, one end of which is connected to a reduction gearbox, and the other end is fitted with a rear shell brake, thereby achieving the rotational drive of the winding shaft through the cooperation of the central motor, the reduction gearbox, and the rear shell brake.

[0009] The present invention is further configured such that the chain drive structure includes a drive sprocket, which is disposed at one end of the winding shaft and the output end of the gearbox. A drive chain is disposed between the two drive sprockets. The rotation drive of the winding shaft can be realized through the cooperation of the drive sprocket and the drive chain, thereby being used for the winding and unwinding of the fireproof roller shutter door.

The central motor and rear housing brake of the drive device are placed between the fixed seat and the pressure seat, and the pressure seat is fastened so that the fixed lug and the locking lug are matched. Then, the locking bolt is rotated so that the locking bolt engages into the locking groove. Then, the locking cap is screwed on so that the locking cap is tightly fixed on the locking lug, thereby realizing the locking and fixing between the locking lug and the fixed lug, thereby realizing the locking and fixing between the pressure seat and the fixed seat, realizing the quick installation of the drive device between the fixed seat and the pressure seat, and facilitating quick disassembly and maintenance.

[0011] The present invention is further provided that the top of the locking cap is provided with a locking knob, and the top of the locking knob is provided with a hexagonal locking block. The cooperation between the locking knob and the hexagonal locking block can improve the ease of turning the locking cap.

[0012] The present invention is further configured such that a limiting block is provided at the outer end of the locking groove in conjunction with the locking cap. When the locking pin is locked and fixed by the locking cap, the limiting block can restrict the locking cap from moving outward, thereby improving the connection and locking stability between the locking pin and the fixing ear and the connecting ear.
